Issue installing DirectX

I just reformatted my computer using a new slipstream cd i made and i am having some issues with iTunes and DirectX.

I have tried the WebSetup for DirectX and the Nov07 redist and both give me this error:

"An internal system error occurred.
Please refer to DXError.log and DirectX.log in your Windows folder to determine problems."

The DXError.log file looks like this:

Code:

--------------------
[11/09/07 11:10:11] module: dxupdate(Oct 22 2007), file: dxupdate.cpp, line: 189, function: GetDXVersion

    Failed API:		RegQueryValueEx()
    Error:		(2) - The system cannot find the file specified.



    Current DirectX may be a older version which does not have the version value in the registry.

--------------------
[11/09/07 11:10:11] module: dxupdate(Oct 22 2007), file: dxupdate.cpp, line: 4504, function: DirectXUpdateDownloadPlugIn

    GetDXVersion() failed.

--------------------
[11/09/07 11:10:12] module: DXWSetup(Oct 22 2007), file: dxupdate.cpp, line: 386, function: DownloadPlugIn

    DirectXUpdateDownloadPlugIn() failed.

    DownloadPlugIn() failed.

Any help would be appreciated. I'm on the verge of just formatting again this time with the regular WinXP cd.
